Poor service

I have signed up for air fibre with MTN and supersonic, I called and app**** to their promotion they were running with free installation and made my upfront payment on the day. I then deactivated/cancelled the current service provider I was using with the impression as they stated that delivery and installation will take place within 7 days.

They called me to confirm installation for the 27th of August and rescheduled it again for the 03rd of September, they then rescheduled again for today the 8th of September and today they calling again to advise me that they won’t be able to install.

How much longer must I wait as it does not seem like they taking me serious and I need this to be done before the end of this current week. I been making arrangements for someone to be available at my place and paying for their time to make sure the installations week on week to happen yet to have no one come and install, I’m very interested to have this service yet I’m being inconvenienced with this and disappointed with this service as my wife and I have other services with MTN but as a customer this is not fair.

I would like someone to make it their priority to make sure this installation happened before Friday the 11th of September 2926
